The old appId method was deprecated in 2012.
To use the Bing Translator with authentication tokens, you first need a server-side script like this PHP script, token.php. It will be called every 9 minutes from the javascript on your web page.
<?php
$ClientID="your client id";
$ClientSecret="your client secret";
$ClientSecret = urlencode ($ClientSecret);
$ClientID = urlencode($ClientID);
// Get a 10-minute access token for Microsoft Translator API.
$url = "https://datamarket.accesscontrol.windows.net/v2/OAuth2-13";
$postParams = "grant_type=client_credentials&client_id=$ClientID&client_secret=$ClientSecret&scope=http://api.microsofttranslator.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postParams);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$rsp = curl_exec($ch);
print $rsp;
?>
Then this html page will display a two-box interface that translates from English to French.
